FM ANTENNAS
FM Outdoor Antennas
Consult with you r dealer or service man about the best
method of selec ting and erecting an outdoor FM antenna.
The choice
of lead-in (feeder) wire is also important. The flat
ribbon-shaped
twin lead performs well electrically. is cheaper
and is
somewhat easier to handle in routing through
windows and around rooms. Coaxial cable is more
expensive. does a
much better job of minimizing interference.
is less prone to the effects of weather and close-by metal
objects. and is nearly as
good a signal conductor as the
ribbon type
wire . The latter is particularly true of foam-type
coaxial cables. Coaxial cable is
somewhat more diff icult to
install at the point where the cable enters the building. If
coaxial cable is selected. make sure the antenna is designed
to dr ive that type of cable. In many cases a matching
transformer (balun) must be used
to connect the antenna
termmals to the coaxial cable.
